Correct, I am not running windows on the mac hardware. Each wow instance has its own subfolder under the main applications folder, they all link back to one data folder, but keep their own settings and such. I set the resolution in the WTF/Config.wtf file. The only additional software I run is CloneKeys. This all runs on a mac pro with the nvidia 8800gt, ram bumped up to 10gb.

As for looting, I set to free for all and just loot everything with main toon. If there are quest drops or BoPs I want for the others, I just click over to whichever window. I don't think there are macro options for looting. I think that requires the mouse.
